If going for the production car land speed record isn't your cup of chai skim latte, there's no need to go for the Brabus Rocket. The Mercedes tuning haus also offers a more sedate build of the AMG CLS63. That is, the S63, which boasts a tuning kit affecting a power boost from 507 hp to to 550 hp and torque from 465 to 479 lb-ft. The exercise involves ECU reprogramming, with a free-flow air filter thrown in for good measure, and results in a slight improvement to its zero-to-60 time (4.3 seconds compared to a stock 4.5 seconds). But gone is the 155 mph limiter, in favor of a 205 mph top speed. The kit will fit on any AMG product with the 6.2-liter V8. It's also Euro IV compliant, you greenie, you.

BRABUS B63 S
550 hp / 404 kW and a Top Speed of up to 330 km/h
for all Mercedes 63 AMG Models

Even more power for all Mercedes 63 AMG models: BRABUS presents its B63 S engine tuning, which boosts power output of the high-revving 6.2-liter V8 to 550 hp / 404 kW and peak torque to 650 Nm. With a sprint time from rest to 100 km/h of just 4.3 seconds and a top speed of 330 km/h a CLS 63 AMG with B63 S tuning turns in performance worthy of a true super sports car.

The BRABUS power kit comprises newly programmed engine electronics with special mapping for injection and ignition. But that's not all: The intake side features a sport air filter for improved supply of combustion air. The exhaust side features high-performance metal catalysts with low back pressure that also ensure that the tuned V8 engine meets stringent EURO IV emission limits.

In order to transfer the increased power to the road with minimum slip BRABUS recommends the BRABUS locking differential for all Mercedes 63 models with rear wheel drive. The diff lock has a locking rate of up to 40 percent.

The BRABUS B63 S performance kit is available for all Mercedes 63 AMG models. With 550 hp / 404 kW the ML 63 accelerates in 4.9 seconds from 0 -100 km/h and reaches a top speed of 275 km/h in combination with the BRABUS V/max unit.

This extraordinary performance represents a good argument for modifications to tires, suspension and brakes. Depending on the Mercedes 63 AMG model in question BRABUS offers custom-tailored tire/wheel combinations up to size 11Jx23 with tires up to 315/25 R 23 in size. To further improve the already excellent handling characteristics BRABUS has developed a control module for the ABC suspensions that lowers the ride height by some 20 millimeters. BRABUS sport stabilizers reduce body roll and optimize turn-in.
